Table attributes Table library is composed of some auxiliary functions.The function uses table as an array.. There are functions for inserting and deleting elements in the list, functions for sorting array elements, and functions for linking all

Property_tree is designed for configuration files. It supports XML, INI, and JSON files. INI is relatively simple and suitable for simple configuration. You may need to save arrays. XML is a good choice. The use of property_tree is also very simple,

StyleStyles is an important tool for organizing and reusing formatting options. Instead of filling the XAML with repeated markup to set details such as margins, colors, and fonts, you can create a series of styles that encapsulate all these details.

When xml_parser is used to read XML, parsing errors may occur if Chinese characters are encountered. There are solutions on the Internet that use wptree for implementation. However, when wptree is used to write XML, an error occurs. When ptree is

The Hungarian naming convention is a naming convention for programming. The basic principle is: variable name = Attribute + Type + object description. Each object name must have a clear meaning. You can take the full name or part of the object name.
